VENTILATING-FRIEZE FOR BLINDS.

Specification of Letters Patent.

Application filed April 10, 1912.

Patented June 24, 1913. Serial No. 689,875.

To all whom 66 may concern:

Be it known that I, JOHN DOUGAN, sergeant of police, a subject of King George V of Great Britain, residing at Imperial Buildings, 3 Dowling street, Dunedin, in the Dominion of New Zealand, have invented certain new and useful Improvements in Ventilating-Friezes for Blinds, of which the following is a specification.

The object of this invention is to introduce apertures providing an air passage between the blind roller and the top of the blind.

In ordinary fittings the blind is attached to a roller pivoted to brackets on the top architrave and except when the blind is fully wound upon the roller any space made by dropping the top sash is covered by the blind; in such instance the opening of the top sash is ineffectual and the object sought is not attained.

In order that the invention may be understood reference will now be made to the accompanying sheet of drawings which are to be taken as a part of the specification and read therewith.

Figure 1 is a perspective iew of the invention showing the ventilating frieze in position. Fig. 2 is a perspective view showing the ventilating frieze wound on the roller. Fig. 3 is an enlarged view of the ventilating frieze.

My invention in its simplest form consists of a band 1 preferably about twelve inches deep, its length being equal to the width of the blind, The band may be constructed of any suitable material, which may be the same as that of the blind and may consist of horizontal top and bottom strips 3 and 3* preferably about one inch wide. The lower strip 3 is preferably double and con sists of two parallel strips or members 4: and 4 arranged side by side to receive between them the upper edge at of the blind Q, the two strips 4 and P, and the aforesaid blind edge 4c being then stitched together. The horizontal strips 3 and 3 are connected together by short vertical strips 5 preferably of the same width and attached to the horizontal strips at equal distances apart, leaving a space 6 preferably of about two inches. These spaces may be cut out, but in that case the edges would be hemmed to prevent fraying.

The frieze may be woven to various designs, ornamental or plain, similar to the ornamental insertion used to decorate the foot of the blind at the present time, and it is preferably manufactured in continuous lengths, from which sections of the proper size to suit the individual blinds may be cut.

The frieze may be readily attached to blinds in use by removing the blind from the roller and inserting the top edge between the folds of the lower horizontal strip and stitching through the three pieces.

The blind is preferably left its full length so that the window may be completely covered if desired.

-What I claim as my invention, and desire to secure by Letters Patent is 1. As a new article of manufacture, a ventilating frieze for attachment to window blinds comprising spaced upper and lower horizontal strips adapted for connec tion, respectively, to the blind roller and the upper edge of the blind, and spaced vertical strips connecting the horizontal strips, the said lower horizontal strip consisting of a pair of parallel members arranged side by side to receive between them the said upper edge of the blind.

2. As a new article of manufacture, a continuous length of ventilating frieze for at tachment to window blinds, from which sections of the proper size to fit the individual blinds may be cut, comprising spaced upper and lower horizontal strips adapted for connection, respectively, to the blind roller and the upper edge of the blind, and spaced ver tical strips connecting the horizontal strips, the said lower horizontal strip consisting of a pair of parallel members arranged side by side to receive between them, the said upper edge of the blind.

In testimony whereof I have hereunto s-e my hand in presence of two subscribing witnesses.
